OK, so I just went to a local floewer shop near my house and I found this worm casting tea. It simply contains 10 hemp bags filled with worm shit. 1 bag per 1 liter of water. I already have a 20% worm casting ratio in my mix. From what I understand the plants absorb all the "good" stuff in the casting and at some time in the grow it is good to add a little more to the top of your soil. Well my question is if I use this as a substitute, at wich point do I put this stuff in? and does anyone have any experience with this stuff.
You can use large amounts of worm tea with basically no draw backs, I have used it in every watering for 3 months and never needed to flush or had any other problems. But so it doesn't just go to waste since already have castings in your soil, just go half strength.
